Intermediary ports have a global shipping network as well as simple inland networks to their
hinterlands. The major cargo of these container ports is the transhipment cargo of other
container ports, but its industrial relations with its backward areas is weak. Intermediary ports
are generally used exclusively by one or a few shipping companies. The intermediary port of
Algeciras relies mainly on transshipment cargo from other countries and is situated at the
crossroads of the shipping routes from Northern Europe, West Africa and Asia. The
commercial relationship with its municipalities in Spain, with the exception of cargo handling
services, is very weak
